Unit testing app extensions iOS8 via framework

So referring to this answer here it is recommended by apple to put all your code in a framework so you can test it.

So my questions are does this have to be an embedded framework or can you create a separate project and put all the extension code in there?

My concern is because upon creating an extension it comes with an info.plist file and an entitlements file and i am unsure where i should be putting those in relation to the framework and such.

Also once you have made the separate or embedded framework project, how do you set the host for your test? mine is mostly interested in the host app being photos, but saying that i need the actual storyboard to load that derives from SLComposeServiceViewController. So would you create an app delegate target that you can set as the host, and then have that load the MainInterface.storyboard of your extension to start the testing?
